, OIL-STOVE.

SPECIFICATION forming part of Letters Patent No. 485,539, dated November 1, 1892.

Application filed February 4, 1892. Serial No. 420,326. (No model.)

T0 00% whom it may concern:

Be it known that I, GEORGE GARDNER, a citizen of the United States, residing at Bolivar, in the county of Polk and State of Missouri, have invented certain new and useful Improvements in Oil-Stoves; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has relation to improvements in oil-stoves; and it consists in the pecullar construction, certain novel combinations, and the adaptation of parts hereinafter described, and particularly pointed out in the appended claims. D

In the accompanying drawings, Flgure 1 1s a perspective View of my improved stove. Fig. 2 is a rear elevation of the same. Fig. 3 is a vertical section taken in the plane indicated by the line no a: on Fig. 1, and Fig. 4 1s a horizontal section taken in a plane immediately below the top of the stove.

In the said drawings similar letters designate corresponding parts throughout the several views, referring to which A indicates the forward corner uprights of my improved stove, which are preferably formed from sheet metal and are preferably of a right-angular form in crosssection for a purpose presently-disclosed. Connected 1n a suitable manner to the transverse portions of the uprights A and extending from the upper end to a point adjacent to the lower ends of said uprights is the front wall B of the caslng, which is also preferably formed from suitable sheet metal. Suitably connected to the longitudinal portions of the uprights A and extending rearwardly therefrom are the side walls 0, which are also preferably formed from sheet metal and have their lower edges inclined upwardly from the front of the stove to a point adjacent to the rear side thereof, where the said edges are horizontal, fora purpose presently set forth. The lower inclined edges of the side walls 0 are reinforced, as 1llu strated, by angle-irons a of a similar form in cross-section to the uprights A, and suitably connected to the inwardly-disposed port on of the said irons dis the bottom wall D, which is inclined upwardly from the front wall B to a point adjacent to the rear wall and serves the vertical flue J in rear of the oven, which serves to lead the heat from the chamber H to the fine I, as well as to assist in heating the oven. Suitably connected, as by bolts, to the rear horizontal portion J of the stove-bottom, which is preferably perforated to facilitate the combustion of the rear auxiliary lamp, are the short angular branches at the ends of the uprights of the rectangular frame K, the horizontal portion of which frame rests upon a floor or other base and serves to support the' rear end of. the stove. Rigidly connected by bolts or the like to the uprights of the frame K and to the inwardly-disposed branches of the inclined angle-irons a are brace-straps b,

which serve in practice to render the said frame K more rigid.

As better illustrated in Fig. 3 of the drawings, the inclined bottom wall D is provided at its forward end with a horizontal portion 0, upon which rests the removable lamp-body M, which is provided with a series of burners d, and has its rear longitudinal wall inclined to conform to the inclined bottom wall D, whereby it will be readily perceived that the lamp will firmly rest in position. Formed in I" the front Wall E of the casing adjacent to the lower end thereof is a door-opening e, through which the lamp M is placed in position, and pivotally connected to the said wall B, at one end of the opening 6, is a swinging door N,

which is provided with a suitable catch, as illustrated, whereby it may be normally held in its closed position. Also formed in the front wall 13 of the casing in alignment with the oven E is a door-opening j, which is normally closed by a swinging door f of the ordinary or any approved construction. the horizontal portion J of the stove-bottom is the auxiliary lamp-body P, which is preferably of a rectangular form in cross-section, as shown, and is provided with a suitable number of burners, which may be of the or- Seated upon dinary or any approved construction. Formed in the rear wall Q of the casing is a dooropening g, through which the lamp-body P is inserted to position, which opening is normally closed by a swinging door R, which may be of any ordinary orapproved construction.

As better illustrated in Fig. 3 of the drawings, a vertical flue S is formed between the transverse wall G and the rear wall Q of the casing, which flue connects the chamber T of the lamp P and the upper horizontal flue I, for a purpose presently disclosed. Connected in a suitable manner to the wall G and the rear wall Q of the casing and extending the full height of the flue S is a partition-wall U, which is arranged at right angles to the said walls and serves in practice to divide the flue S into two halves, for a purpose presently disclosed. Journaled in. suitable bearings upon the upper edge of the walls G G on opposite sides of the partition-wall U are rock-shafts V, to which are fixed damperplates V, which are manipulated through the medium of the said shafts to control the fines on opposite sides of the wall U. The ends of the shafts V take through the side walls of the casingand are preferably formed into cranks, as shown, whereby they may be readily rocked and the dampers manipulated. Formed in the top wall F of the stove-casing are a series of potopenings m, and also formed in said wall adjacent to the front wall of the casing is a series of small openings at, which are preferably arranged in a transverse line and serve in practice to permit an escape of the hot air after it has passed around the oven, whereby it will be seen that a draft will be created and the combustion of the lamps increased.

In the practice of my invention when a moderate degree of heat is needed for the oven the lamp M is lighted and the damperplates IV are closed, whereby it will be readily perceived that the hot air will be led directly from the chambers H through the fine J to the flue I, whereby it will be seen that the oven will be surrounded by hot air and a high even heat maintained. When a very high heat is desired for the oven, the auxiliary lamp P is lighted, together with the lamp M, and the damper-plates W are opened, whereby it will be perceived that the heat will be greatly increased.

When heat is desired for heating pots or the like upon the top of the stove, the damperplates W are opened and the auxiliary lamp P alone employed, as the heat therefrom is led directly to the upper horizontalfiueI and is sufiicient for the purpose stated. When it is desired to heat pots on one side of the stove top without heating those upon the other side thereof, one of the damper-platesWis closed and the other plate on the same side as the pots to be heated is opened. The burners on one side of the lamp P are then lighted and their heat is conducted directly to the pot to be heated, whereby it will be perceived that a great saving of fuel is efiected.

From the foregoing description it will be perceived that I have provided an exceedin gly cheap and simple stove embodying such a construction and such an arrangement of flues, &c., that the degree of heat may be nicely regulated and an economy of fuel thereby effected.

Having thus described my invention, what I claim, and desire to secure by Letters Patcut, is-

1. In an oil-stove, substantially as described, the combination, with the casing, the oven, the chamber II, arranged beneath the oven, the lamp in said chamber, thehorizontal flue I above the oven, and the vertical flue J, connecting the chamber II and flue I, of the transverse wall G, the transverse wall G, the chamber T, the lamp in said chamber, the vertical flue S, and a damper pivotally mounted at the upper edges of the walls G G, substantially as and for the purpose set forth.

2. In an oil-stove, substantially as described, the combination, with the casing, the oven, the chamber H, arranged beneath the oven, the lamp in said chamber, the horizontal flue 1 above the oven, and the vertical flue J ,connecting the chamber H and flue I, of the transverse wall G, the transvere wall G, the chamber '1, the lamp in said chamber, the vertical flue S, the partition-Wall U, dividing the flue S into halves, and the dampers pivotally mounted at the upper edges of the walls G G and adapted to be independently actuated or manipulated, substantially as specified.

- In testimony whereof I affix my signature in presence of two witnesses.

GEORGE GARDNER.
